Definitions

  • the present invention relates to a combine harvester according to the preamble of claim 1.
  • the combine harvesters have distribution devices designed as driven radial distributors, to which the crop to be distributed is fed by a chopper device.
  • the EP 2 298 061 A2 describes a combine harvester with a distribution device according to the preamble of claim 1.
  • the combine harvester comprises a chopping device downstream, driven by at least one drive train distribution device having two rotationally driven conveyors.
  • the two conveyors accept a crop stream leaving the chopper and redirect it to the outside.
  • the Erntegutstrom of the respective conveyor downstream of one of these fed to a pivotable about the longitudinal axis of the combine parallel pivot axis distribution device.
  • the distribution devices can be transferred from their operating position into a transport position pivoted at an angle of 90 ° about their pivot axis. In this transport position, the distribution devices are perpendicular to the respective conveyor.
  • This transport position of the distribution devices may be problematic in terms of compliance with the maximum permissible width of the combine. In particular, however, occur due to this transport position of the distribution elements when moving the combine forces that must be absorbed by the brackets of distributors.
  • the distribution device ensures compliance with the permissible overall width in its transport position and is also characterized by a simple and lighter structure.
  • a combine harvester with a chopper and one of these downstream, driven by at least one drive train distribution device comprising rotating driven conveyors accept and deflect a leaking from the chaff device crop stream to downstream of the Erntegutstrom one of the respective conveyor by means of an actuator to supply a pivotable parallel to the longitudinal axis of the combine axis pivoting distribution device, proposed.
  • the combine harvester is characterized in that the distributing devices can be transferred by pivoting about their pivot axis from at least one operating position into a transport position and vice versa, in which the distributing devices have a parallel or nearly parallel arrangement occupy above the respective conveyor, without interrupting the drive train between the conveyors and the distribution devices.
  • the actuators need only be designed such that they can transfer the respective distribution device in the transport position and hold in this.
  • the holding in this transport position is supported by the parallel or nearly parallel arrangement above the respective conveyor since the conveyors can serve the tray.
  • In the transport position of the distribution devices of the actuators is essentially the task to prevent a swinging. In contrast to the prior art, it does not require the complex compensation of acting on the distribution devices dynamic forces in the transport position, especially during road travel of the combine.
  • Operating positions of the distributing devices are understood to be the positions which the distributing device and with it the conveying devices and the downstream distributing devices can occupy with respect to the chopper device when chopped crops are to be spread over the working width of the combine harvester or untreated straw, which is separated from a separator device Combined harvester bypassing the chopper and the distribution device is to be stored in the form of a swath on the ground.
  • the respective distributor can be pivotable in the direction of the longitudinal axis of the combine harvester by an angle of greater than 170 °, in particular 180 °. This ensures that the center of gravity of the distribution device is in its transport position above the conveyors. In their operating position they are preferably arranged in each case next to a conveyor.
  • the drive train of the distribution device remains connected in the transport position of the distribution devices. That is, when changing the distribution devices between one of the operating positions and the transport position, a separation of the drive train is not required.
  • eliminating the closing of the drive train to transfer the distributor of the transport position in one of the operating positions can.
  • the transfer between one of the operating positions and the transport position of the distribution devices is simplified. Since the transfer of the distribution devices from the at least one operating position into the transport position and back without interruption of the drive train can be realized, the cost of this for an operator is extremely low.
  • a manual intervention of an operator to disconnect the drive train for example by releasing a clutch, in particular a dog clutch, to interrupt the drive train between the conveyors and the distribution devices, is not required.
  • eliminates a manual intervention to close the drive train This also has the advantage that can be dispensed with costly measures to protect the open coupling halves against pollution and other external influences.
  • a power transmission means may be arranged in the drive train of the distribution device at least between the respective conveyor and the downstream of this distribution device, which causes during the transfer and in the transport position, a maintenance of the power flow.
  • the distribution devices are in a defined operating condition, thereby an uncontrolled tracking of the distribution devices can be avoided after switching off a drive unit serving the drive of the distribution device. In the transport position, the distribution devices can not move.
  • the drive train mechanically formed at least between the respective conveyor and the respective downstream distribution device be. It is particularly advantageous if the complete drive train of the distribution device is mechanically formed.
  • the power transmission means may be formed as a propeller shaft.
  • a propeller shaft allows the maintenance of the power flow even when transferred to the transport position, so that the distribution devices occupy a defined operating state.
  • the propeller shaft is characterized by a relatively small space requirement.
  • the PTO shaft is wear and maintenance. It also requires no special protection against pollution or other external influences.
  • the power transmission means may be formed as a finger clutch.
  • the finger clutch is characterized by a relatively small space requirement.
  • an electrically, electromechanically or hydraulically actuated actuator system can be provided for the alternate transfer between the at least one operating position and the transport position of the respective distribution device.
  • the actuator system is preferably designed as a respective hydraulic cylinder, the supply of which is effected by a hydraulic circuit of the combine harvester.
  • a control device which is set up to actuate the actuators in such a way that the respective distribution device is transferred alternately between the at least one operating position and the transport position.
  • the control device may be part of a control and regulation device of the combine, which is operable by an operator.
  • the transfer of the distribution device from the at least one operating position to the transport position can be automatically controlled by the control device when a so-called road driving mode is activated by the operator by a corresponding input to the control and regulation device of the combine. Conversely, when the road driving mode is deactivated appropriate.
  • a manual control for changing between the at least one operating position and the transport position is provided by the control device.
  • control device can be set up to control the actuator system in order to transfer the distributor device into a distribution position.
  • the distribution device for dispensing opening of the chopping device is oriented such that a substantially tangential transition of the chopped crop from the chopping device to the conveying devices of the distribution device takes place.
  • control device can be set up to actuate the actuators such that the respective distributor device is transferred into a swath-depositing position as a further operating position.
  • the swathing position straw is stored in the form of a swad, bypassing the chopping device on the ground.
  • the distributing device takes a position inclined downwards to the chopping device in order to allow the straw to slide along the upper side of the distributing device onto the ground.
